Abstract

The present invention provides three-dimensional picture images without using lenticular lenses etc. In addition, this liquid crystal display device has a transparent picture screen so that remote display picture images or three-dimensional picture images of high luminance are seen multiplexed with the background. The display device is constructed by arranging picture elements in which volume-phase type holograms are formed by a periodical construction of liquid crystals and polymers. By the way, to get the more clear image. Diffraction light from first picture element groups which are distributed uniformly reaches a left eye of an observer while diffraction light from second picture element groups which are distributed uniformly reaches a right eye of an observer. The condition of the picture elements are switched to diffract irradiated light or to transmit the light, thus a desired picture image comprising a dot matrix can be displayed. The first picture element groups display parallax picture for the left eye, and the second picture element groups display parallax picture for the right eye.
